Correction: It's Watanabe Miyuki
There are some inconsistencies that may require clarification.The romanji and kanji (渡辺美優紀 = Miyuki Watanabe) refer to two different people. They both have PBs of their own.Also, while the preview pictures shows Miyuki Watanabe, the filename refers to Mayu Watanabe. I can't download at the moment, so I can't check who it really is in the file.
Hi, it is not Mayuyu's PB, it's Miyuki Watanabe one.
title corrected. thanks
